Discover the LOXJIE D40 PRO and its Revolutionary Audio Technologies

Unleashing Superior Sound with Cutting-Edge Technologies

The LOXJIE D40 PRO is a game-changer in the world of audio, offering unparalleled sound quality and a host of advanced technologies. With features like MQA-CD ES9039MSPRO XU316, DSD512, Bluetooth LDAC, APTXHD, I2S, and AES, this DAC (Digital-to-Analog Converter) sets a new standard for audio excellence. In addition, it comes with a convenient remote control, ensuring seamless control over your audio experience.

A Comprehensive MQA Decoder

The LOXJIE D40 PRO serves as a complete MQA decoder, providing an immersive listening experience by fully expanding MQA music files. With this decoder, you can now hear the content created by artists in the studio as intended. Through popular software platforms like TIDAL and Roon, you can easily play MQA music, and with the CD file size decoded, you can enjoy high-quality music at a remarkable 352.8kHz.

Furthermore, the LOXJIE D40 PRO also supports MQA-CD, allowing users to connect to compatible CD players via optical or coaxial connections and enjoy high-quality MQA music.

Optimal Performance through High-End Chip Optimization

At the heart of the LOXJIE D40 PRO lies the ESS ES9039 MS Pro decoding chip. This 32-bit high-fidelity stereo DAC is specifically designed to deliver exceptional audio performance. With integrated MQA support, it satisfies even the most discerning audiophiles. Through meticulous optimization, the D40 PRO achieves an impressive THD+N rating of -125dB (un-weighted), ensuring pristine audio reproduction.

DPLL Function for Enhanced Clock Stability

The LOXJIE D40 PROalso boasts a DPLL (Digital Phase-Locked Loop) function, providing users with seven types of PCM filters and four types of DSD filters. By adjusting the clock stability of the input signal, users can enhance the system's performance. When the clock stability is optimal, reducing this value improves the system's overall clock performance. On the other hand, if the input signal's clock stability is compromised, increasing this value can effectively prevent sound interruptions, ensuring a smooth and uninterrupted audio experience.


Professional-grade headphoneamplifier Output volume is independent.Fully balanced

The headphone amplifier has two levels of adjustable gain: high and low.When set to high gain, the balanced interface has a +20dB increase, while the unbalanced interface has a +14dB increase.Additionally, the outputimpedance is close to 0Q.
The independent volume function allows you to freely control the soundlevel of both the headphones and line outputs, helping to prevent hearing damage caused by excessive volume. The line output magnitudeis 2.5Vrms for RCA and 5.2Vrms for XLR.
